Kuchisake-onna

Region/Culture: East Asia (Japan)
Mythos: Japanese Mythology, Urban Legends & Contemporary Folklore
Primary Type/Nature: Undead/Cursed Beings
Mythical Attributes: A masked vengeful ghost who stops people on dark streets, asks whether she is pretty, and slits the mouth of anyone who answers wrongly.
Role in Mythos: She is the archetypal Japanese urban legend, a beautiful woman disfigured in life who returns as an onryō to inflict her own wound on strangers.
Relation to Humans: The Kuchisake-onna hunts ordinary people, most often children walking home alone after dark, and her question offers no safe reply. She is escaped only by those who know the rules, answering vaguely or distracting her long enough to run.

The street is empty except for the tap of low heels on wet pavement and a child coming home late from cram school. A woman is waiting near the cold glow of a vending machine, tall and neatly dressed, a surgical mask over the lower half of her face like half the country wears in flu season. There is nothing wrong with her at all until she speaks. She wants to know if she is pretty. Her voice is soft and reasonable, and the question hangs in the night air, and there is no right way to answer it.

She is the Kuchisake-onna, the slit-mouthed woman, and she has been walking Japanese streets in the retelling for longer than most of the people afraid of her have been alive. The ritual is fixed and it is short. She stops you, she asks whether she is beautiful, and she waits. Say no and she takes it badly. Say yes and she peels the mask away to show you a mouth opened from one earlobe to the other, a raw grin the width of her whole face, and asks again through the ruin of it: even now? Say no this time and she kills you. Say yes and she decides you should have a mouth like hers, and she comes at you with the scissors.

To picture her is to picture something almost ordinary, which is the worst part. She looks like a woman you might stand beside on a train. Long dark hair, a good coat, sometimes a long trench, the mask that hides everything until she chooses to lower it. The scissors are the tell, oversized tailor’s shears in most tellings, though other versions arm her with a kitchen knife, a sickle, or a scalpel. When the mask comes down the illusion collapses at once. The cut runs clean past the corners of her lips into the cheeks, wet and red, and when she smiles the smile does not stop where a smile should.

Her origins are as slippery as the rumor itself, and the stories do not agree. The oldest threads reach back into the Edo period and further, to a beautiful woman married to a samurai, unfaithful or merely suspected of it, whose jealous husband slit her mouth ear to ear and asked who would think her lovely now. Other accounts blame a rival rather than a husband, a jealous woman or a sister taking a blade to her face. A colder, more modern version drops the samurai entirely and gives her a botched cosmetic or dental procedure, a surgery that went wrong and left her mutilated and enraged. In some tellings she died on the operating table, which is where one of the stranger details comes from: she is said to loathe the smell of pomade, the greasy hair oil worn by the doctor who ruined her. However she was made, she came back an onryō, one of the vengeful dead of Japanese belief, and she came back wanting company in her disfigurement.

What lifted her out of old ghost stories and into a genuine national fright was the year 1978, when the rumor surfaced in Gifu Prefecture and began to move. By the summer of 1979 it had swept the country. Newspapers and weekly magazines reported it in earnest, from the Gifu Nichi Nichi Shinbun that January to the Shukan Asahi and the Shukan Shincho that spring. Children walked home in groups. Police increased their patrols and schools arranged escorts, and in Himeji a woman was arrested wandering with a knife and a mask, as if the story had decided to make itself real. The folklorist Iikura Yoshiyuki has traced how it spread so fast: as more families sent their children across the city to evening cram schools, the schools mixed kids from everywhere, and the tale traveled with them from district to district faster than any single neighborhood could contain it. A bogeyman for the walk home in the dark.

The legend is unusual in that it comes with instructions for survival, and the escape tricks are as much a part of her as the scissors. The clean solution is to refuse the trap of the question. Answer neither yes nor no but something in between, “so-so,” “average,” “you’re ordinary,” and the ambiguity stalls her long enough to run. She has appetites that can be used against her. She is fond of bekko-ame, a hard amber candy, and will stop to take it if you throw some down. She hates pomade, and shouting the word three times, or six, is said to make her falter. You can turn her own move back on her by asking whether she thinks you are pretty. And you can climb, because the second floor of a building is often said to be beyond her.

Her powers are few but they are enough. She appears where she likes after dark, she cannot be reasoned with, and she is fast. The most repeated figure gives her a hundred meters in six seconds, which means the child who answers wrong does not outrun her. She carries the certainty of the trap: both honest answers end with a blade. Yet for a terror she is oddly bound. She obeys the rules of her own game, pausing for a sweet, tripping over a word she hates, stumped by an answer that will not commit. A clever reply beats her where courage cannot. Whatever she was before the mouth, she is now a wound looking for someone to share it with, and the only defense is to give her nothing clean to cut.

Frequently Asked Questions

Who is the Kuchisake-onna?

The Kuchisake-onna, meaning “slit-mouthed woman,” is a vengeful spirit or onryō of Japanese folklore and urban legend. She is depicted as a woman whose mouth has been cut from ear to ear, hidden behind a surgical or cloth mask, who accosts people on dark streets and asks whether she is pretty before attacking those who answer wrongly.

What does the Kuchisake-onna ask, and what happens if you answer?

The Kuchisake-onna asks “Am I pretty?” while wearing her mask. If the person says no, she attacks. If they say yes, she removes the mask to reveal her slit mouth and asks again; a second “no” gets the victim killed, and a “yes” prompts her to cut the victim’s mouth to match her own. There is no straightforwardly safe answer.

How do you escape the Kuchisake-onna?

The most common escape is to give a noncommittal answer such as “so-so” or “average,” which confuses her long enough to flee. Other methods include throwing bekko-ame candy, which she likes and will stop for, shouting the word “pomade” several times because she hates it, asking her whether she finds you pretty, or getting above the second floor of a building.

Where did the Kuchisake-onna legend come from?

The story has old roots, often traced to the Edo period, in which a beautiful woman’s mouth was slit by a jealous samurai husband, a rival woman, or in modern versions a botched cosmetic or dental procedure. She returned as an onryō, a vengeful ghost, seeking to inflict her disfigurement on others.

Why did the Kuchisake-onna cause a panic in 1979?

A rumor about the Kuchisake-onna surfaced in Gifu Prefecture around 1978 and spread nationwide by the summer of 1979, reported in newspapers and magazines and fueled by children carrying the story between cram schools across the city. The scare led to heightened police patrols and school escorts, and in one case a woman was arrested in Himeji wandering with a knife and a mask.
